TECHNICAL FIELD

The technology disclosed relates to handling of components in an SMT system and the receiving and providing of information related to a Surface Mount Technology (SMT) job. In particular, the technology disclosed relates to a display (e.g., an alphanumerical display) associated with a carrier for carrying component tapes held by a component tape reel and the sending of instructions related to an SMT job as well as the changing of display data related to an SMT job.

BACKGROUND

Surface Mount Technology is now the preferred method of automated production of electronic printed circuit boards. Machines for pick-and-place mounting of components on a substrate, such as a Printed Circuit Board (PCB), or a substrate for a System in Package (SiP) component are subject to different, often contradictory demands, such as mounting speed, mounting precision, size, prize, etc. The expression “pick and place” is understood by the person skilled in the art as describing the very mounting operation where a mounting head is moved to a component feeder area, where the mounting head picks one or more components from one or more of the component feeders, and then is moved to a mounting area where the mounting head places the component or components on the substrate.

Supplies of a certain type of component (e.g., a certain specified type of capacitor, resistor, diode, IC, etc.) are supplied on trays carrying one type of component or on sticks or, as has become most common today, on tapes in reels with a series of pockets of appropriate depth in the tape, holding one component in each pocket. The reels have varying widths between about 8 mm and about 44 mm. A row of reels, each reel representing a different type of component, are placed in a bin which in turn is placed in a magazine and feed components into the pick-and-place machine as the nozzle arms rapidly pick components out of their pockets and place them on the board. Component manufacturers deliver the components in standard reels of pocket-tape with a thin cover tape closing the pockets. This pocket cover tape must be removed by some method before the component can be picked out of its pocket.

Tape guides or feeders are used to feed the tape into the pick-and-place machine as the components are picked out of the pockets. One such tape guide or feeder is described in EP 1 381 265 B1, incorporated herein by reference. This type of component tape guide or feeder has no built-in tape advancing mechanism. Rather, the tape guide or feeder is mounted for use in the pick-and-place machine so that a feeding mechanism, e.g. a feeding wheel in the pick-and-place machine protrudes through the tape guide or feeder into contact with the pre-threaded tape. Another type of component tape guide has a built-in tape advancing mechanism. The tape guide or feeder is mounted for use in the pick-and-place machine so that an in-feeder built-in feeding mechanism or tape advancing mechanism advances the tape, e.g. a feeding wheel in the feeder into contact with the pre-threaded tape.

Each tape guide or feeder has a specific identity in relation to the pick-and-place machine and in whatever sequential position the reel with its pre-threaded tape guide or feeder is placed in the machine, the mounting machine robotics will properly find and pick-up the proper components from the tape pockets. A method of associating the identity of the tape guide or feeder used to the specifics of the components in the tape threaded into the guide or feeder is described in EP 1 147 697 B1, incorporated herein by reference.

Generally, within the field of manufacture and assembly of circuit boards, electronic components are fed to a component mounting machine for mechanically and/or electrically mounting the components onto a circuit board. These surface mounted components are often delivered spaced apart along the length of a component tape. Generally, two different types of component tapes are used. The first type consists of a lower carrier tape, preferably plastic, provided with component holding compartments, which are enclosed by a separable, thin, plastic upper cover, or cover tape or protective tape.

The second type consists of a cardboard body provided with through holes. The body is provided with separable, thin, plastic, top and bottom cover tapes, thus forming component compartments with the through holes. For ease of description, the term cover tape will hereinafter

After having positioned the electronic components in their corresponding compartments, the cover tape is attached to the carrier tape, and the component tape is wound on a component tape holder, which within the art generally consists of a component tape reel. The attachment of the cover tape to the carrier tape can, for instance, be performed by providing either or both of the cover tape and the carrier tape with adhesive areas, or by fusing the cover tape to the carrier tape. Then, the component holder is transferred to a component mounting machine, which feeds a component to a certain predetermined picking position where it can be picked, or collected, by a pick-up head.

According to a method conventionally used within the art, the loading of a component tape in a component mounting machine involves the following steps: Placing the component tape reel into the reel holder of a component mounting machine, or into a tape magazine of a component mounting machine; introducing the free end of the component tape into a feeding mechanism, provided in the machine or in the magazine, such that feeding pins engage corresponding holes provided in the component tape; separating, by hand, the end of the cover tape from the end of the carrier tape for a distance sufficient for the cover tape to be engaged with a cover tape handling device, generally a bobbin onto which the cover tape can be wound; and lowering a locking mechanism over the carrier tape for holding the carrier tape against the feeding mechanism.

Another method that also has been suggested involves, briefly, the steps of loading a component tape of a component tape reel into a tape guide, placing the component tape reel into the reel holder of a component mounting machine or into a magazine, and mounting the tape guide into the machine and/or the magazine.

In both these methods, the magazine or the portion of the component mounting machine into which a component tape to be used in a mounting process is loaded must be idle during the loading process. If a large number of component tapes are to be loaded, the idle time may be significant.

Bins, as an example of a carrier in the technology disclosed, are in conventional systems used to house a row of reels in a magazine as the pick-and-place machine picks components out of the pockets of the pocket-tape. A bin has a predefined number of slots adapted to receive component tape reels. One such bin is shown in WO03024181 A1, incorporated herein by reference.

An object of the technology disclosed is to provide a more efficient and less error-prone method and system for handling changeovers and replenishment work associated with a Surface Mount Technology (SMT) job.

SUMMARY

The technology disclosed relates to improved handling of components in an SMT system. In particular, technology disclosed is to provide a more efficient and less error-prone method, system and device for handling changeovers and replenishment work associated with a Surface Mount Technology (SMT) job.

Certain aspects of the technology disclosed relate to a method, system and device for changing information related to an SMT job on a display.

According to certain aspects of the technology disclosed, the at least one display, which is attached to or associated with a carrier (e.g., a bin) allows operators to receive and/or change information on said display (e.g., the operator may receive just-in-time information about electronic components and material) anywhere on the shop floor (e.g., by means of a wireless communication link). The SMT system may thereby guide the operator through an entire loading, kitting or changeover process by presenting instructions on displays (e.g., electronic labels). As a result, operators can work more efficiently and instantly locate missing components and material (e.g., by sending a signal directly to the display).

In other aspects of the technology disclosed, the display associated with the carrier is further configured to receive instructions from the operator by the action of pushing a pressure-sensitive button (on or associated with the display, e.g., by being logically, wirelessly or electronically connected to the display) and/or scanning a barcode (on or associated with the display, e.g., by being logically, wirelessly or electronically connected to the display). The operator may thereby provide the SMT system (e.g., via a Wireless communication link) with updated information through a loading, kitting or changeover process by sending instructions using the interface of the displays (electronic labels). As a result, operators can work more efficiently and in a less error-prone manner and be guided by the SMT information database (and his own and other operators' actions providing the SMT database and/or a separate IR/WLAN-based system with updated information) through the entire loading, kitting or changeover process by sending instructions to the displays and/or uplink (e.g., via a communication network) to the SMT information database.

Yet another aspect of the technology disclosed is to receive instructions (e.g., triggering further actions associated with an ongoing and/or upcoming SMT job and/or the SMT information database) from an operator regarding an ongoing and/or upcoming SMT jobs. The carrier of the technology disclosed (e.g., a bin or trolley having a plurality of predefined number of slots adapted to receive component tape reels) may then be used as a means for receiving instructions, or input data, from an operator and/or the SMT information database regarding an ongoing and/or upcoming SMT jobs.

Another object of the technology disclosed is to provide improved feedback to an operator and/or the SMT information database regarding an ongoing and/or upcoming SMT jobs. The carrier of the technology disclosed, (e.g., a bin or trolley having a plurality of predefined number of slots adapted to receive component tape reels) may then be used as a means for providing improved feedback to an operator and the SMT information database regarding an ongoing and/or upcoming SMT jobs while the pick and place machine is performing an SMT job and without interrupting production.

The technology disclosed offers a solution, wherein said bins are adapted to each comprise vertically oriented pallets and a display (e.g., facing the operator) and where input data relating to an SMT job is received and display data based on the received input data is presented on said display.

Optional aspects of the technology disclosed include that the tapes may be pre-threaded into the proper tape guides or feeder and that each component tape reel is, or is associated, by coding, suitably bar coding, with its tape guide or feeder, which in the continued processing will be for the pick and place machine the reel with the proper components. Association may be performed between Bin ID, Pallet ID, component tape reel ID and tape guide ID/SMT component feeder ID by storing the IDs in a data structure in an SMT information database.

Other optional aspects of the technology disclosed include that the component tape reel and the pre-threaded tape guide will be coded together in the SMT information database and stored as a bin load unit in an automated SMD storage warehouse, either as a packet unit, comprised in a pallet and/or comprised in a bin or trolley. The bin or trolley may be retrieved from the automated SMD storage warehouse and placed into a magazine of the pick-and-place machine.

In certain other optional aspects of the technology disclosed, a set of pallets is provided, wherein each pallet comprises a component tape reel with and optionally a pre-threaded tape guide, are fitted into a pallet bin and stored in an automated SMD storage warehouse. The pallet bin may be retrieved from the automated SMD storage warehouse and placed into a magazine of the pick-and-place machine. Previously, the correct set of individual tape reels and feeders or pallets comprising tape reels and feeders as a unit, coded together, had to be selected by the operator, who is setting up an SMT job, and inserted into its proper component feeding position in the magazine of the machine. In the case with individual tape reels and feeders, the correct tape guide (of some 20 different guides) had to be selected by the operator, who is setting up an SMT job. In addition, the barcode of the delivered reel and the identity of the tape guide will have to be linked. Then the operator will have to thread in the component tape properly, before inserting the tape guide into its proper component feeding position in the machine. All of these time-consuming and possibly error-prone steps are eliminated by the system and method according to optional aspects of the technology disclosed, whereby pre-fitted bins, or trolleys (e.g., pallet bins comprising a suitable set of pallets comprising components for scheduled SMT jobs) are retrieved from the automated SMD storage warehouse. The pre-threading and associating component tape reel is by coding, suitably bar coding, with its tape guide or association in an SMT information database and placement into pallets is done by trained storage personnel, which may load the entire SMD Tower with up to thousands of reels of component tapes with paired feeders as individual pallets or as a part of a set of pallets in a pallet bin.

DETAILED DESCRIPTION

The invention relates to Surface Mount Technology (SMT) systems and SMT methods in the field of Surface Mount Technology are now the preferred method of automated production of electronic printed circuit boards. Such a system may typically comprise an SMT information database, an SMT pick and place machine, an automated Surface Mount Device (SMD) warehouse and optionally an SMT job planning computing device, wherein all the nodes mentioned above are communicatively coupled (e.g., in a communications network).

SMT pick and place machines for pick-and-place mounting of components on a substrate, such as a Printed Circuit Board (PCB), or a substrate for a System in Package (SiP) component are subject to different, often contradictory demands, such as mounting speed, mounting precision, size, prize, etc. The expression “pick and place” is understood by the person skilled in the art as describing the very mounting operation where a mounting head in said SMT pick and place machine is moved to a component feeder area, where the mounting head picks one or more components from one or more of the component feeders located at predetermined component feeder positions at the pick and place machine, and then is moved to a mounting area where the mounting head places the component or components on the substrate. The total task of placing all required components to a predetermined number of substrates is referred to as producing an SMT job. The SMT job typically comprises SMT job data descriptive of all required components, the position of each component on a substrate required to produce SMT production units, such as electronic printed circuit boards, and the planned relative order the SMT job should be produced in (e.g., third in order to be produced out of five planned SMT jobs).

A typical workflow in a SMT system, as the one described above, is that a planning user plans an SMT job to be executed, stores said SMT job in an SMT information database, an SMT operator (i.e., a human being or alternatively a robot) retrieves required components from said automated Surface Mount Device (SMD) warehouse, transfers required components (e.g., placed on component tape reels) to the pick and place machine and loads predetermined component feeder positions at the pick and place machine (e.g., magazines or trolleys) of said SMT pick and place machine and start SMT production of SMT production units (i.e., substrates with SMT components placed thereupon).

The technology disclosed relates to a method, a system and an arrangement for handling component tapes in connection with mounting components onto circuit boards in a component mounting machine, which utilizes a carrier in form of a bin for carrying component tapes. Each component tape is held by a component tape reel. The component mounting machine utilizes component magazines or a trolley from which components, carried by the component tape, are supplied for use in a mounting process of the component mounting machine. The component tape of each component tape reel is loaded into a tape guide or component feeder for guiding the component tape in the component mounting machine, and the component tape reels are arranged in the bin, which thereafter is placed in the magazine. The tape guides, or component feeders, are then mounted in the magazine such that the component tape loaded therein may interact with feeding devices provided in the magazine. Accordingly, the magazine is loaded with components and prepared for the ensuing mounting process.

To operate the SMT system, the operator is responsible for monitoring the production of the SMT production units, retrieving components from the SMD warehouse and inserting components in positions in the SMT pick and place machine. Today these tasks are performed by manual methods such as printouts. There is a need to provide the operator with dynamic information (e.g., into which position a retrieved component should be inserted in the SMT pick and place machine or which components that are about to run out when the SMT pick and place machine is in production of SMT production units). With improved information obtained by the operator, the risk of erroneous insertion in the SMT pick and place machine can be reduced and the time required to stop the production to replace a component tape reel can be reduced.

According to certain aspects of the inventive concept disclosed, the carriers (in form of a bin or basket for carrying the components held by a component tape reel) are provided with at least one alphanumerical display (e.g., an electronic label) configured to change information that said alphanumerical display is showing in order to provide the operator of the component mounting machine with dynamic information (e.g., into which position a retrieved component should be inserted in the SMT pick and place machine or which components are about to run out when the SMT pick and place machine is in production of SMT production units). With improved obtained by the operator, the risk of erroneous insertion in the SMT pick and place machine can be reduced and the time required to stop the production to replace a component tape reel can be reduced.

When producing SMT production units in an SMT system, a SMT job associated with an SMT production unit is planned or predefined and stored in an SMT information database. Information relating to an SMT job might indicate the number of production units to be produced and component requirements to complete production of the SMT unit by an SMT pick and place machine. In conventional systems this involves retrieving individual component rolls carrying SMT components, transporting and inserting them in a component feeding position at the pick and place machine, where they can provide components to the pick and place machine robot. The invention reduces the complexity and error-prone previous process by providing pre-loaded bins, trays or accumulator devices that are automatically retrieved from the automated Surface Mount Device (SMD) warehouse and presented at a port, slit, outlet or access point to the operator of the pick and place machine, and can be inserted directly into the pick and place machine for the upcoming SMT job. As the bins have been pre-loaded with components required at the upcoming SMT job, less actions are required by the operator. Information relating to upcoming SMT jobs is obtained, for example, retrieved from memory, pushed or sent by the SMT information database over a communications network, retrieved over a communications network from the SMT information database and/or obtained from operator indications to an input/output device of the automated Surface Mount Device (SMD) warehouse.

The third bin load unit compartment section 1532 can be separated from the fourth receptacle compartment section 1531 and inserted back into the fourth receptacle compartment section 1531 at a later time. The bin 1510 comprising a third load unit compartment section 1532 inserted into the fourth receptacle compartment section 1531 can be inserted directly into the pick and place machine for producing the upcoming SMT job. By replacing the third load unit compartment section 1532 with a different one (e.g., a third load unit compartment section 1532 configured to receive component trays, component sticks or component tape reels), the bin can be more easily reconfigured to be loaded with different type of components depending on requirements of an SMT job.

FIG. 4 shows illustrates an example embodiment of a method in a Surface Mount Technology (SMT) system comprising an automated Surface Mount Device (SMD) warehouse 93, an SMT information database and a SMT pick and place machine 91. In this example, the method comprises: receiving input data; retrieving a bin 410 based on said input data and a parameter representing a position within said automated Surface Mount Device (SMD) warehouse, wherein said bin 410 is adapted to comprise bin load units 420, wherein said bin load unit 420 comprises at least a component tape reel; presenting said retrieved bin 410 at a port 97 of said automated Surface Mount Device (SMD) warehouse; and loading said bin 410 in said SMT pick and place machine 91.

FIG. 5 shows a schematic view of pre-loaded bins 510 (e.g., pre-loaded based on component requirements of an upcoming SMT job) being inserted or loaded into component feeding positions 520, 530 and 540 of the pick and place machine 550.

To pre-load the bins to improve, optimize or prepare for presentation at a port of the automated Surface Mount Device (SMD) warehouse based on upcoming SMT jobs, thereby ensuring that the components required for production of an SMT production unit are present when the bin is presented, the bin load units are redistributed within the same bin or between two or more different bins. The advantage is that bins can be pre-loaded for upcoming SMT jobs, and the retrieval time in the tower can be reduced by placing bins required for the next upcoming SMT job close to the port and certain components can be distributed in different automated Surface Mount Device (SMD) warehouses.

In some embodiments, the bins might comprise pallets that in turn comprise component tape reels and optionally a matching SMT feeder.

In some aspect of the technology disclosed, the bin might be adapted with an alphanumerical display controller that is adapted to receive display data by wired or wireless communication, wherein the data might be relating to an upcoming SMT job and displayed to the operator. The data may include: the position at the pick and place machine where the bin should be inserted; time or date; the number of remaining components remaining in the bin; an alert to replace the bin or manually refill the bin with bin load units; or other alarm conditions relating to production of SMT production units.

The information (e.g., component requirements) used to pre-load bins and present bins at a port of the automated Surface Mount Device (SMD) warehouse might be entered by the operator via a input/output device comprised in the automated Surface Mount Device (SMD) warehouse or obtained from the SMT information database, either actively retrieved by request/reply or pushed from the SMT information database or other node connected to the communication network.

When the automated Surface Mount Device (SMD) warehouse receives a bin, the processor comprised in the automated Surface Mount Device (SMD) warehouse stores, in a memory, the position at which the bin is stored to a memory (e.g., in automated Surface Mount Device (SMD) warehouse).

The automated Surface Mount Device (SMD) warehouse comprises one or several actuators, such as a robot, robot arm or other actuator, as would be understood by a person skilled in the art. The actuators are able to redistribute bins or bin load units within the automated Surface Mount Device (SMD) warehouse or between connected automated Surface Mount Device (SMD) warehouses.

In some aspect of the technology, disclosed bins might be brought to a designated intermediate redistribution area where bin load units might be redistributed within or between two or more bins.

In some aspect of the technology disclosed, more than one actuator might be comprised in the automated Surface Mount Device (SMD) warehouse, thereby enabling insertion in fully loaded bins, for example, by first removing a first bin load unit with a first actuator and filling the empty position in the same bin with another bin unit by a second actuator, similar to how a human being would redistribute bin load units between bins. Obviously, the process might involve one two or several bins until the redistribution is complete.

FIGS. 12a and 12b shows schematically how in an embodiment, bin loading units, denoted by letters A-D in FIGS. 12a and 12b , are redistributed among two or more stored bins in the automated Surface Mount Device (SMD) warehouse based on, for example, component requirements of upcoming SMT jobs.

In this example, FIG. 12b illustrates how bins 1220-1250 are pre-loaded based on the component requirements of upcoming SMT jobs (e.g., job A, job B, job C and job D), and FIG. 12a illustrates the bin loading units after being redistributed among the two or more stored bins in the automated SMD warehouse according to the upcoming SMT jobs.

FIG. 13 shows an example of how bin loading units may be redistributed between two or more stored bins in the automated Surface Mount Device (SMD) warehouse (e.g., by being brought to a designated intermediate redistribution area where bin load units might be redistributed).

Referring to FIG. 13, the actuator or robotic arm 13104 of the automated Surface Mount Device (SMD) warehouse grips a load unit 13103 in a first bin 13101 and moves the load unit 13103 to a compartment in a second bin 13102 as illustrated by image sequence 1310 through 1370 in FIG. 13.

FIGS. 14a and 14b shows an example of how bins may be redistributed between positions in the automated Surface Mount Device (SMD) warehouse based on component requirements of upcoming SMT jobs. In one example, a SMT job list or sequence of job D, job A, job C and job B are to be performed. By redistributing the bins from the arrangement shown in FIG. 14a to the arrangement shown in FIG. 14b , the retrieval time for the bin pre-loaded for SMT job D can be reduced as the distance to the port is reduced.

FIG. 16 shows an example of how bin load units are automatically redistributed between positions in the automated Surface Mount Device (SMD) warehouse using a table 1630.

Referring to FIG. 16, a first stored bin 1610 is retrieved to the table 1630 attached to an actuator in said automated Surface Mount Device (SMD) warehouse, and said actuator is moved to a position of a second stored bin 1620 within said automated Surface Mount Device (SMD) warehouse.

The second bin 1620 is retrieved to the table 1630, and the bin load units are automatically redistributed between positions in the automated Surface Mount Device (SMD) warehouse using a table by redistributing bin load units from said first bin 1610 to said second bin 1620.

FIG. 17a shows an embodiment of the invention, wherein a bin 1710 is configured with an alphanumerical display 1720 with an integrated alphanumerical display controller, and an identity tag 1730 attached to the bin 1710 such that a bin ID can be obtained. In one example, this identity tag 1730 is a barcode.

FIG. 17b shows an embodiment of the invention, wherein a bin 1710 is configured with an alphanumerical display 1720 with an integrated alphanumerical display controller, wherein display data on the alphanumerical display comprises a bin ID, wherein said bin ID is presented as a barcode, QR code or the like. Thus, the alphanumerical display 1720 also functions as an identity tag of the bin. In one or more embodiment, the communications network ID of the alphanumerical display 1720, used to send data to and receive data from the alphanumerical display controller, is identical to the bin ID.

FIG. 18 shows an embodiment of a pallet 1810.

Referring to FIG. 18, the pallet 1810 comprises a backplane 1811 and a component tape reel retainer structure in the shape of a box. The box is configured with a bottom 18121, four side walls 18122 and a slit 1840 configured to allow a component tape 1830 on a component tape reel 1820 protrude through the slit 1840. In one or more embodiments, the pallet 1810 further comprises a friction break (not shown) configured to engage upon removal of said palette from said SMT pick and place machine, hereby suppressing and/or preventing unwinding of the tape when the reel is no longer feeding components to a pick-and-place machine.

The inventors have realized that with the rising complexity of SMT production comes a greater need for quality data. High part number count, a wide variety of boards, and an ever-changing production schedule are constant challenges that require improved system support and control of information handling. Through embodiments presented herein, there is achieved efficiency and service level from a customer or operator point of view, in the performing any or all of the steps of planning, associating, loading, replenishing and/or unloading as part of an SMT production process.

FIGS. 19a-19d show schematically how planning, associating, loading, replenishment and unloading may be performed in accordance with a use case example of a typical workflow in a SMT system.

Referring to FIGS. 19a-19d , a planning user starts the workflow by planning an SMT job to be executed, and stores said SMT job in an SMT information database. In a use case example referring to FIG. 19a , a planning operator uses an SMT planning tool, for example, a graphical user interface of a computer program that is adapted to help the user optimize the job sequence and changeover strategy for incoming orders to plan an SMT job. The outcome of the planning is typically a bill of materials 1910 (also referred to herein as SMT job data). The bill of material/SMT job data is sent to the automated SMD warehouse 1912 (e.g., corresponding to the SMD warehouse 93 discussed herein).

In response to receiving the bill of materials/SMT job data, the automated SMD warehouse 1912 automatically delivers bin load units 1914 (e.g., in the form of any of the bin load units 420, 620, 630, 640, 650, 720 described herein). In this use case example, the bin load units 1914 are in the form of component tape reels. Typically, the bin load units delivered from the automated SMD warehouse are already in the correct order for loading into bins. An SMT operator (e.g., a human being or alternatively a robot) then retrieves the bin load units that are delivered from said automated Surface Mount Device (SMD) warehouse, and possibly also substrates from separate storage or from said automated Surface Mount Device (SMD) warehouse. In the use case example, the SMT operator retrieves component tape reels from the automated SMD warehouse 1912, and prepares the component tape reels for loading into the pick and place machine 1924. In order to be able to trace the component tape reels, the preparations include a step of associating the ID of each component tape reel with the ID of a feeder 1919. The SMT operator performs this association by scanning each component tape reel and a corresponding feeder using an identity tag scanner 1918. Through scanning of the unique IDs, the SMT system records the movement of the scanned components. Accordingly, components are automatically traced.

When the bin load units have been associated with the feeders, the SMT operator places the one or more associated component pairs into a bin 1920. The bin may, for example, correspond to any of the bins 410, 510, 610 or 710 discussed herein. When a bin is ready, the SMT operator places/loads the bin in the pick and place machine 1924. The pick and place machine may correspond to any of the pick and place machines (e.g., 91, 550) discussed herein.

In order for the pick and place machine to know which settings are to be used, SMT job data from the planning step is provided to the pick and place machine, either directly from the planning tool or by the SMT operator scanning the barcode of a work order 1922, using a scanner 1918, comprising the required information/SMT job data. This is illustrated in FIG. 19 b.

Based on the input SMT job data, machine programs are selected automatically, as are conveyor width and loader/unloader settings. In other words, loading into the pick and place machine is fast and easy for the SMT operator as it requires no manual data entry—just one or two scans of barcodes or other identifiers. As soon as the line is up and running, the SMT operator is free to start preparing the next SMT job. Also, as all bins and feeders are given a unique ID, the SMT operator can check quantity, location, MSD data and batch codes, for a single component or a complete component list for an SMT job, at any point during production.

If, at any time, components are about to run out, the machine alerts the operator, re-optimizes and continues mounting other components. The SMT operator that notices such an alert may, for example, press a “provide” button or the like, whereby the SMD warehouse 1912 immediately delivers the requested component/components 1914 for the SMT operator to retrieve, associate and load into the pick and place machine 1924 to replenish the machine. This is illustrated in FIG. 19c . Advanced SMT system of today, such as the system embodiments described herein, may also have a plug-and-play simplicity, which means that the SMT operator can load and unload bins in seconds, saving countless hours of operator time. Specially designed software automatically recognizes the presence, absence and location of components, which means that there is no need to program pick positions and production does not stop if a bin runs out of parts.

As illustrated in FIG. 19d , when an SMT job is done, or when the work day ends, the SMT operator unloads the bins 1920 from the pick and place machine, removes the component tape reels 1914 from the bin and places them back into an SMD warehouse 1912, which can be the same as the one from where the components where retrieved or a different one. As each component has an identifier, the system keeps track of the components and mix-ups are avoided.

Embodiments of the invention may improve parts or all of the SMT production workflow, as further described herein.

FIG. 3 shows a method for presenting a retrieved bin at a port of an automated Surface Mount Device (SMD) warehouse in Surface-mount technology (SMT) system. In more detail, FIG. 3 shows an example of the technology disclosed in the form of a method in an automated Surface Mount Device (SMD) warehouse adapted to obtain information related to upcoming SMT jobs, to store bins at predetermined positions within said automated Surface Mount Device (SMD) warehouse and to retrieve bins at predetermined positions within said automated Surface Mount Device (SMD) warehouse, wherein said bins are adapted to comprise bin load units, wherein said bin load unit comprises at least a component tape reel.

Referring to FIG. 3, at 300 the automated Surface Mount Device (SMD) warehouse receives input data. At 310, the automated Surface Mount Device (SMD) warehouse retrieves a bin based on said input data and a parameter representing a position within said automated Surface Mount Device (SMD) warehouse. In at least this example, said bin is adapted to comprise bin load units, wherein said bin load unit comprises at least a component tape reel. At 320, the automated Surface Mount Device (SMD) warehouse presents said retrieved bin at a port of said automated Surface Mount Device (SMD) warehouse.

In one non-limiting example, the input data received at 300 may be descriptive of one or more sets of components, component 1, component 2, . . . component P. A bin is retrieved based on said input data and a parameter representing a position within said automated Surface Mount Device (SMD) warehouse. In one example, the parameter may be comprised in a data structure stored in the SMD warehouse, such as a table, descriptive of a component tape identity, bin identity or pallet ID and a position within said SMD. Example parameters are shown below in Table 1.

TABLE 1 Identity X-position Y-position Z-Position Component tape Identity 1 X1 Y1 Z1 Component tape Identity 2 X2 Y2 Z2 Component tape Identity 3 X3 Y3 Z3 Component tape Identity 4 X4 Y4 Z4

In another example, the parameter may be comprised in a data structure, such as a table, descriptive of a component tape identity, bin identity, pallet ID, and/or a position within said SMD. An example in which the parameter includes a shelf ID is shown below in Table 2.

TABLE 2 Identity Shelf ID Component tape Identity 1 S1 Component tape Identity 2 S2 Component tape Identity 3 S3 Component tape Identity 4 S4

The X, Y, Z position or the shelf ID of the component tape may be obtained by performing a look-up in the parameter table based on the input data to obtain the position within said automated SMD warehouse (e.g., (X1,Y1,Z1), (Shelf 34), etc.). The bin or bins located at the obtained position within said automated SMD warehouse are then retrieved and presented at a port of said automated Surface Mount Device (SMD) warehouse.

The automated Surface Mount Device (SMD) warehouse may further comprise an input/output interface and said input data is received from said input/output interface based on an operator indication of an upcoming SMT job.

In one example, an operator enters the identity of an upcoming SMT job, and the automated Surface Mount Device (SMD) warehouse retrieves or receives the identities of components associated with, comprised in or required in the upcoming SMT job from said SMT information database, such as component tape reel identity or pallet identity. The X, Y, Z position or the shelf ID may be obtained by performing a look-up in the parameter table based on the retrieved or received identities of components to obtain the position within said automated SMD warehouse, (e.g., (X1,Y1,Z1), (Shelf 34), etc.). The bin or bins located at the obtained position within said automated SMD warehouse are then retrieved and presented at a port of said automated Surface Mount Device (SMD) warehouse.

In one or more examples of the technology disclosed, said input data is received or retrieved from an SMT information database and said input data is associated with or included in an upcoming SMT job.

In one example, the input data descriptive of an upcoming SMT job is pushed by or received from the SMT information database via the communications network, the automated Surface Mount Device (SMD) warehouse retrieves or receives the identities of components associated with, comprised in or required in, the upcoming SMT job from said SMT information database, such as component tape reel identity or pallet identity. The X, Y, Z position or the shelf ID is obtained by performing a look-up in the parameter table based on the retrieved or received identities of components to obtain the position within said automated SMD warehouse (e.g., (X1,Y1,Z1), (Shelf 34), etc.). The bin or bins located at the obtained position within said automated SMD warehouse is then retrieved and presented at a port of said automated Surface Mount Device (SMD) warehouse.

In one or more examples of the technology disclosed, said parameter represents a position within said automated Surface Mount Device (SMD) warehouse, and is retrieved from a memory in said automated Surface Mount Device (SMD) warehouse.

In one example the parameter representing a position within said automated Surface Mount Device (SMD) warehouse is an X, Y, Z position and/or the shelf ID, and is obtained or retrieved by performing a look-up in a parameter table based on the retrieved and/or received identities of components to obtain the position within said automated SMD warehouse (e.g., (X1,Y1,Z1), (Shelf 34), etc.).

In yet another embodiment, there is provided a method in an automated Surface Mount Device (SMD) warehouse adapted to obtain information related to upcoming SMT jobs, to store bins at predetermined positions within said automated Surface Mount Device (SMD) warehouse and to retrieve bins at predetermined positions within said automated Surface Mount Device (SMD) warehouse. Said bins are adapted to comprise bin load units, and said bin load units comprise at least a component tape reel. The method comprises: receiving at least one of input data and a parameter representing a position within said automated Surface Mount Device (SMD) warehouse; retrieving a bin loaded with a plurality of bin load units from said position within said automated SMD warehouse at least partly based on said at least one of input data and/or a parameter representing said position within said automated Surface Mount Device (SMD) warehouse; and presenting said retrieved bin at, or close to, an output port, such as an opening, of said automated Surface Mount Device (SMD) warehouse.

At time t1, the first actuator 2030 transports said bin or bin load unit 2050 to said first opening 2011. Further, said first actuator 2030 releases the grip of the bin or bin load 2050 unit in a position where said bin or bin load unit protrudes into said second opening 2021 in said second Surface Mount Device (SMD) warehouse 2020. Alternatively, the first actuator 2030 in the first automated Surface Mount Device (SMD) warehouse releases the grip of the bin or bin load unit 2050 in the first opening 2011.

At time t2, a second actuator 2040 in the second automated Surface Mount Device (SMD) warehouse 2020 is configured to grip the bin load unit 2050 protruding into said second opening 2021 in said second Surface Mount Device (SMD) warehouse 2020. Alternatively, the second actuator 2040 in the second automated Surface Mount Device (SMD) warehouse 2020 is configured to grip the bin or bin load unit 2050 in the first opening 2011 such that bins or bin load units can be redistributed from said first Surface Mount Device (SMD) warehouse 2010 and said second Surface Mount Device (SMD) warehouse 2020.

Identifying a Bin in an SMT System

When an operator is returning a bin to the automated Surface Mount Device (SMD) warehouse, there is a need to determine the bin load units in the bin by scanning a bin ID and retrieving the associated bin load units ID, such as pallet ID, component tape reel ID and SMT feeder ID, from an SMT information database.

When an operator is retrieving a bin from the automated Surface Mount Device (SMD) warehouse, there is a need to associate a bin ID with the bin load units ID's, such as pallet ID, component tape reel ID and SMT feeder ID, by scanning a bin ID and storing the associated bin load units ID's, such as pallet ID, component tape reel ID and SMT feeder ID, to an SMT information database.

One or more aspect of the technology disclosed provides a method in an automated Surface Mount Device (SMD) warehouse configured to store bins at predetermined positions within said automated Surface Mount Device (SMD) warehouse, the method comprising: receiving a bin at a port of said automated Surface Mount Device (SMD) warehouse; and scanning an identity tag (e.g., in form of an electronic display) attached to said bin to obtain a bin ID.

In one or more aspect of the technology disclosed, the method further comprises: storing said bin at a position within said automated Surface Mount Device (SMD) warehouse.

In one or more aspect of the technology disclosed, the method further comprises: storing said position and said bin ID in a memory of said automated Surface Mount Device (SMD) warehouse.

One or more aspect of the technology disclosed describes a method in an automated Surface Mount Device (SMD) warehouse adapted to obtain information related to upcoming SMT jobs, to store bins at predetermined positions within said automated Surface Mount Device (SMD) warehouse, the method comprising: receiving a bin at a port of said automated Surface Mount Device (SMD) warehouse; scanning an identity tag attached to said bin to obtain a bin ID; storing said bin at a position within said automated Surface Mount Device (SMD) warehouse; and storing said position and said bin ID.

In yet another aspect of the technology disclosed, the method further comprises: presenting said retrieved bin at a port of said automated Surface Mount Device (SMD) warehouse.

In yet another aspect of the technology disclosed, said bins are adapted to comprise bin load units, wherein said bin load unit comprises at least a component tape reel.

In yet another aspect of the technology disclosed, storing said position and said bin ID further comprises storing said position and said bin ID represented as parameters, such as a table, in a memory of said automated Surface Mount Device (SMD) warehouse.

In yet another aspect of the technology disclosed, storing said position and said bin ID further comprises storing said position and said bin ID represented as parameters in an SMT information database via a communications network.

In one or more embodiments, a bin is configured with an electronic display such as alphanumerical display, with an integrated display controller, and a printed identity tag attached to said bin such that information relating to an SMT job is displayed and a bin ID can be obtained by scanning (e.g., optically scanning a barcode) the printed identity tag.

In one or more embodiments, a bin is configured with an electronic display such as an alphanumerical display with an integrated alphanumerical display controller, display data may comprise information about the reels carried by said bin and/or a bin ID, and said bin ID is presented as an optically scannable code such as a barcode, QR code or the like.

In one or more embodiments, an alphanumerical display functions as an identity tag of the bin. In one or more embodiments, the communications network ID of the electronic display, used to send data to and receive data from the electronic display controller, such as an electronic alphanumerical display, is identical to the bin ID.

In one or more embodiments, scanning comprises scanning an optically scannable code such as a barcode, QR code or the like, and the optically scannable code is presented on a printed label or an electronic display such as an electronic alphanumerical display.

In one example, the electronic display (e.g., an electronic alphanumerical display) is attached to a bin and displays an electronic barcode representing a unique bin ID of the bin and/or that the electronic display is further representing and showing SMT job related information to the operator (e.g., information about each of the individual bin load units, such as component tape reels) stored in one of the compartments of the bin.

Conventional electronic shop/shelf label (ESL) systems are configured based on an infrared (IR) scheme, low frequency band communication, or radio frequency (RF) band communication. Such conventional ESL systems may have a degraded accuracy when reading or updating information of a plurality of ESL tags based on an environment of the store, for example, an obstacle within the store, and may increase complexity and/or costs for facility infrastructure.

More specifically, to update ESL tag information within the store (e.g., to update details), conventional ESL systems may use between one reader (or antenna) to tens of readers (or antennas) based on a radio communication scheme or a frequency difference. Also, when conventional ESL systems employ an IR scheme, a relatively large number of readers may be required, thereby increasing a facility costs and an area where reception is impossible may occur depending on the store environment.

When the conventional ESL systems employ an RF scheme (e.g., at 2.4 GHz), reception may be impossible in certain areas depending on the store environment. In addition, due to a short battery lifespan, battery replacement costs may also be incurred.

At least one example embodiment provides an electronic shelf label (ESL) system using radio frequency identification (RFID) that may store, in an ESL tag attached to a shelf, SMT job information received from an ESL server, thereby readily updating the details included in the ESL tag/display, and an operation method of the ESL system.

At least one other example embodiment provides an ESL system using RFID that may obtain identification information of a bin load unit, such as a component tape or component tape reel positioned on a shelf, from a component tape recognition tag attached to the component tape, and provide the obtained identification information to an ESL server, thereby enabling a manager to readily plan and manage SMT-related jobs/actions involving the stored component tape (e.g., replenishment work, loading a bin with reels in the compartments of the bin, preparing for a SMT pick-and-place Job) and to effectively manage and provide instructions related to the component tape and decrease a cost used for managing human resources, and an operation method of the ESL system.

An ESL system using RFID, may include: an ESL tag to be attached to a shelf; and a radio tag reader to store, in the ESL tag, details received from an ESL server (e.g., originating from the SMT information database), in response to an SMT information update request from the ESL server (or SMT information database via a separate ESL system to the shelf tags/displays).

An operation method of an ESL system using RFID may include: receiving details regarding an SMT job from an ESL server together with an SMT job information update request from the ESL server; storing the received details in an ESL tag attached to a shelf; and displaying the received details.

An ESL tag according to one or more example embodiments may include, or be associated with, one or more pressure sensitive buttons to enable an operator to change the information displayed on the ESL tag and dynamically update SMT-job related information, which frequently varies.

The pressure sensitive buttons may be used to confirm actions, trigger actions, and/or modify the content of the display itself. Pressing of the pressure sensitive buttons may send an immediate trigger to an external system, or store information to be sent at a next scheduled communication event (e.g., a periodic communication event). The action may also be local and change between predefined information sets.

In more detail, for example, an operator may use the pressure sensitive buttons to confirm an action related to the display (e.g., component picked from a shelf location) without using a barcode scanner (having both hands free for picking the related object). In another example, the operator may use the pressure sensitive buttons to change the displayed content immediately, for example, from component name to component quantity or next action for the object.

According to one or more example embodiments, the pressure sensitive buttons may include one or several buttons, and may be mechanical, optical, electrical, touch screen, etc.

In response to pressing of the pressure sensitive buttons, the ESL tag may inform a controlling system (e.g., base station and related software that a button on the ESL tag has been pressed) save the button pressed information to be available at the next scheduled communication event, and/or directly trigger a change in the display on the ESL tag between predefined messages.

An ESL tag attached to a shelf may store details (e.g., SMT job related information) received from an ESL server, thereby readily updating the details included in and/or displayed on the ESL tag.

FIGS. 26a through 26f illustrate various ESL tags according to example embodiments. As shown in FIGS. 26a through 26f , the ESL tags may include pick and place information, such as one or more of slot, kit name, location, bin name, bin barcode, component name, etc. The pick and place information may be arranged as desired on the ESL tag.

According to one or more example embodiments, the ESL tags may be arranged on component shelves, bins, trolleys, bin load units, pallets, SMT pick and place machines, etc.

FIG. 27 illustrates a component shelf 2700 along with an ESL tag 2702 arranged thereon. As shown, the ESL tag 2702 may include a component name, component type, quantity of components on the shelf, a container name associated with the component, and a barcode. The information provided to the ESL tag 2702 by an operator may be sent to the ESL server wirelessly.

FIG. 25 is a perspective view of a stick magazine 2106 including an ESL tag 2104 arranged thereon.

FIG. 21 illustrates a portion of a pick and place machine including two bins 2110 and 2112 and a stick magazine 2106. As shown in FIG. 21, the bin 2110 has an ESL tag 2102 arranged thereon. The bin 2112 includes a magazine 2108, and has an ESL tag 2100 arranged thereon. The stick magazine 2106 has an ESL tag 2104 arranged thereon.

FIG. 29 illustrates a dry storage unit including ESL tags for each location on each shelf of the unit. The ESL tag may display the shelf location content and be configured to change appearance as discussed herein.

According to one or more example embodiments, identification information of a component tape reel positioned on a shelf may be obtained from a component tape ESL tag attached to the shelf edge. The obtained identification information may be provided to an ESL server, thereby enabling the ESL system (IR-based or RFID-based) to readily perform inventory of component tape reels stored at storage positions/shelves, push down to the ESL tags (e.g., a display touch screen an electronic dynamic label) on the shelf edges associated with a stored component tape reel and (dynamically through event-triggered automatic pushed down instructions) change SMT job related information on the displays. Therefore, it is possible to effectively manage and trace component tape reels and thereby decrease costs for managing human resources.

E-label tags/electronic displays, according to one or more example embodiments, display shelf location content in form of SMT job related information similar to smart labels on shelves for easy component tape fetching. An IR-based or RFID-based Electronic Shop/Shelf Label (ESL) system may be used to provide (e.g., dynamically/automatically changing) the SMT job related information (from the SMT information database) on the displays (e.g., during a kitting process, a replenishment process, when loading a bin with component tape reels in preparation of a pick-and-place job).

The above ESL, where the SMT operator preparing SMT pick-and-place jobs have an input possibility on (or associated with) an external display unit, where the input mechanism may be one or several buttons (mechanical, optical) or a touch screen on the display itself, and where the internal action of the operator may be at least one of: direct sending a button pressed message to a controlling system (base station and related software, the SMT information database via an IR and/or RFID-based ESL system); saving the button pressed message to be available at the next scheduled communication event; and directly triggering a display content change (e.g., between predefined messages).

The e-labels may be configured to (dynamically/automatically) change their appearance to clearly indicate to the SMT job operator where to pick the needed components for an upcoming SMT pick-and-place job (e.g., based on pushed down instructions from the SMT information database using or via a separate ESL system or the operator's pushing of a button), the electronic displays will dynamically change from dark to bright, change its color, indicate in which order the component tapes (bin load units) shall optimally fetched by the operator from the shelves or stored in compartments of a bin (for storing component tape reels).

FIGS. 28a through 28d illustrate examples of four e-labels. As shown, the e-label in FIG. 28b is an example in which e-label has dynamically changed from bright to dark based on pushed down instructions from the SMT information database using or via a separate ESL system or the operator's pushing of a button.

The shelves for storing component tapes (e.g., component tape reels, or “bin load units” in form of packets comprising a reel with a component tape pre-threaded into a tape guide/SMT component feeder), where at least one electronic label/tag is attached to a shelf edge for each storage location on each shelf.

In certain aspects the invention, the technology disclosed allows for the use of at least one sensor/detector for detecting/indicating when/whether a component tape reel is fetched from (or stored at) the storage location on the shelf (by the operator or a robot) and send uplink information to the ESL system (to be forwarded to SMT information database system), or send it directly to the conventional SMT information database system.

This revolutionary Mycronic enhancement to the material handling process will significantly reduce the effort of bringing and keeping track of components (improved traceability) during kitting and replenishment process.

By using modern E-paper labels information about the various phases during materiel handling will be displayed just in front of the operator when he needs the information

With the Smart e-labels it is possible to show operator what to do independently if the bin is in the machine or in the kitting area.

The e-labels can also be used to show what you have on your shelves and guide you collecting those components.

At least one other example embodiment provides a smart barcode scanner display configured to display SMT job related information (e.g., direct instructions to the operator) when scanning a barcode (e.g., on a component tape reel, a pallet for carrying a component tape reel or an electronic shelf label/display) during, for example, a kitting process, a replenishment process, when loading a bin with component tape reels in preparation of a pick-and-place job, etc.

FIG. 30a is a perspective view of a barcode scanner according to an example embodiment.

Referring to FIG. 30a , the barcode scanner 3000 includes a handle 3100, a trigger 3060, a scanner input device 3040, a display 3020, and input buttons 3080. The barcode scanner 3000 may also include a memory, a processor, and a wireless transceiver to communicate wirelessly with a ESL system.

The smart barcode scanner 3000 with the display 3020 may be used to display SMT job related information to the SMT operator in order to guide the operator on what to do with an object (e.g., a component tape reel) corresponding to the scanned barcode. This enhancement to the material handling process by the provision of guidance to the operator (e.g., sequentially provided and/or event-based triggered guidance SMT job related information) provides improved traceability and/or less error-prone kitting and replenishment processes.

An IR-based or RFID-based ESL system may be used for providing (e.g., dynamically/automatically changing) the SMT job related information from the SMT information database on the barcode scanner display 3020.

When preparing for upcoming SMT pick-and-place jobs, the SMT operator handling the barcode scanner 3000 with the display 3020 may also have an input possibility on (or associated with) a barcode or an external display unit, where the input mechanism may be the scanning of a barcode (e.g., a conventional barcode on a component tape reel or on (or associated with) an ESL display itself) by the scanner device 3040, and where the barcode scanning action of the operator may be sending data (e.g., through IR or RFID data) to a controller unit associated with the barcode or an external display unit. The controller unit may trigger: sending direct uplink SMT job related information to a controlling system (e.g., a base station and related software, the SMT information database via an IR and/or RFID-based ESL system); saving SMT job related information to be available at the next scheduled communication event; or directly triggering the display content on the barcode scanner display to change (e.g., between predefined messages).

The trigger 3060 may be used to activate the scanner device 3040 to perform a scanning operation. The buttons 3080 may be used to modify/update information on the display 3020, and transmit the updated information to the ESL system to update the ESL database.

The barcode scanner display 3020 may be configured to change its appearance to more clearly indicate to the SMT job operator where to pick the next component tape reel (or SMT packet) for an upcoming SMT pick-and-place job. In one example, the barcode scanner display 3020 may change its appearance in response to the scanning of a barcode by the operator or pushed down instructions from the SMT information database using or via a separate ESL system or the operator's pushing of a button. The barcode scanner display 3020 may automatically/dynamically change from dark to bright and/or change its color to indicate to the operator in which order the component tapes (bin load units) should be at least one of: loaded into a bin; fetched by the operator from storage shelves in a kitting or replenishment process; or stored in an automatic SMD component warehouse including a robot.

The ESLs discussed herein may be e-paper labels.

The barcode scanner display 3020 may show an operator what to do independently if the bin is in the machine or in the kitting area (e.g., during a replenishment process or kitting process). The barcode scanner display may also be used to directly show what the operator has on the shelves, and sequentially guide the operator in collecting the component tape reels.

One or more example embodiments may enhance the material handling process to reduce the effort of bringing and tracking components during kitting and replenishment processes (e.g., improved traceability and more efficient and less error prone SMT job related actions performed by the operator).

FIGS. 30b through 30d illustrate example displays output on the display of the barcode reader. In more detail, FIG. 30b illustrates example content displayed when scanning a carrier for loading into a pick and place machine. FIG. 30c illustrates example content displayed when scanning a feeder for loading. FIG. 30d illustrates example content when scanning an action barcode.
